You have to click once on the choice you make, and then click on button "OK" so to validate your choice. This makes two actions, when it would be possible to validate your choice with only one action — ie the double-click. STEPS TO REPRODUCE 1. Display a dialog box for the choice of one single item in a list, ie kdialog --radiolist 2. Double-click on the choice you want to validate OBSERVED RESULT The line is selected, but not validated, you have to click on "OK" so to validate it. EXPECTED RESULT The choice is validated, just like if "OK" had been clicked.
